Silicone Rubber 3 Core Cable Terminations
6.6kV 11kV 15kV 33kV IEC
3M 7600-T-3W
3M 7600 Cold Shrink Series 3 Core (Three Conductor) Cable Terminations
3M Cold Shrink termination kits are designed to accomodate medium/high voltage 3 core shielded, copper tape screened or armoured power cables.
3M 7600-3W Cable Termination Kits using Cold Shrink for cables without ground wires and 3M 7600-RJS Termination Kits cabinet-mounted for cables with or without ground wires. With exception of high voltage cable lugs, which can be selected from the Cembre 2A Copper Cable Lugs range, each 3M Cold Shrink termination kit is supplied with all the materials required for terminating one 3 core (three conductor) cable.

3M Cold Shrink cable termination components include :
3M Cold Shrink QT-III Cable Termination—a one-piece cold shrink assembly that consists of skirted or tubular insulator, high dielectric constant (Hi-K) stress control tube, conformable Hi-K stress control mastic and a built-in silicone cable lug sealing compound. The complete Cold Shrink assembly is pre-stretched and loaded onto a removable plastic core. Core removal allows the cable termination assembly to shrink down and seal onto prepared cable phase insulation and cable lug barrel surfaces.

3M Cold Shrink QT-III Cable Termination - Features and Benefits
3M Cold Shrink QT-III Cable Termination - Applications
3M 7600 Series QT-III Cold Shrink Cable Terminations are designed to accommodate three conductor (3 core) power cables ranging from No. 8 AWG (8sqmm) at 3kV to 500 KCMil (240sqmm) at 35kV.
Cold shrink terminations are compatible with the following solid dielectric insulation types : Polyethylene (high and low density), cross-linked Polyethylene (XLPE) and ethylene propylene rubber (EPR).
3M Cold Shrink cable terminations are light weight suitable for both free-hanging and bracket-mount, stand-off insulator type arrangements.
3M 7600 Cold Shrink Cable Terminations are available for both protected and weather-exposed areas. The amount of airborne contaminant determines the severity of the cable termination operating environment and may influence its long term performance. Operating environments are defined as light, medium, heavy and extremely heavy according to pollution severity. Selecting the appropriate termination depends on system voltage and operating environment.

HV Cable Jointers Tips : Cinch constant force springs onto copper tape screen earth braid connection for effective bonded earth. View end of high voltage cable through finger cores to ease high voltage cable insertion. Spread cable phases while sliding cable boot breakout to ease the cable termination installation. Do not damage QT-III Cold Shrink termination while cutting RJS re-jacketing sleeve, sleeve assembly can be rotated to ease trimming. When high voltage cable lug spade dimension is larger than the inside diameter of the white plastic cable termination core, position the cable termination over cable phase legs prior to installing lugs. Do not push or pull the Cold Shrink termination while unwinding - continuously guide the Cold Shrink maintaining sleeve-to-cable-core alignment.
